Naphthylazonaphthol dyes which contain a 5-chloro-6-fluoropyrimidin-4-yl reactive group

Abstract

Reactive dyestuffs of the formula ##STR1## produce bluish red dyes having excellent fastness properties on hydroxyl- and amido-containing fibre material.

We claim: 
     
       1. Reactive dyestuff which, in the form of the free acid, has the following formula 
     
     
       2. Reactive dyestuff according to claim 1 of the following formula ##STR16## 
     
     
       3. Reactive dyestuff according to claim 1 of the following formula ##STR17## 
     
     
       4. Process for dyeing and printing fibre materials with a dyestuff, comprising applying there to a dyestuff according to claim 1. 
     
     
       5. Process according to claim 4, wherein the fibre material contains hydroxyl groups and/or amido groups. 
     
     
       6. Fabric based on a hydroxyl- and/or amido-containing material, wherein the material has been dyed or printed with a dyestuff according to claim 1.
